Los Angeles: US actress Jennifer Aniston married her long-time boyfriend, fellow actor Justin Theroux, in a surprise ceremony in front of family and friends at their California home, People magazine reported Thursday.

The wedding took place Wednesday at the couple’s home in the Bel Air neighborhood of Los Angeles, before about 70 guests, the celebrity magazine reported, citing unnamed sources.

‘Guests were told it was a birthday party for Justin,’ one source told People. ‘Jen and Justin wanted to surprise guests and guests were certainly surprised.’

Among the invitees was Aniston’s one-time ‘Friends’ co-star Lisa Kudrow and comedian Chelsea Handler.

Aniston, 46, and Theroux, who will be 44 next week, started dating in 2011, as they were filming the movie ‘Wanderlust.’ They were engaged a year later.

It is the second marriage for Aniston, who married Hollywood heartthrob Brad Pitt in 2000 — forming one of Tinseltown’s most glamourous couples at the time.

They divorced in 2005 after Pitt met his current wife, Angelina Jolie, on the set of ‘Mr & Mrs Smith.’

Representatives for Aniston and Theroux did not immediately comment when asked to confirm the report.
